Definitions

  • the invention relates to a method for removing suspended matter from gases in a chamber with tangential gas inlet and axial gas outlet or axial gas inlet and tangential gas outlet, an axis-centric rotary atomizing device by means of which washing liquid is introduced into the gas stream in droplet form and brought into contact with the suspended matter. It also relates to devices for performing the method.
  • DE-AS 1 o35 621 describes a gas preparation stage, referred to as a humidification chamber, through which the gas to be treated flows axially, with a certain rotational movement being impressed on the gas by tangential entry and exit.
  • the washing liquid is atomized very finely by an atomizing device.
  • the atomizer device is arranged in the center of the axis and, according to the illustration, consists of several rotating atomizer disks, the top of which is acted upon by washing liquid.
  • the function of the other panes is not clear from the illustration. This procedure has the disadvantage that the advantages of the rotary movement of the gas due to the essentially axial gas routing are not used consistently.
  • the insufficient effectiveness for the separation of suspended matter is also proven by the use only as a humidification and preparation chamber.
  • the invention has for its object to treat gases loaded with suspended matter in a chamber with a washing liquid so that the contact -washing liquid / gas suspended material- is optimized by targeted system-internal measures and centrifugal means.
  • a method is proposed according to the invention, which is characterized in that the washing liquid is introduced evenly distributed over the entire chamber depth into the gas stream, the washing liquid amount is 1.5 11m3 to lo l / m 3 gas and the washing liquid entry in the gas flow takes place at a speed of 2o m / s to 12o m / s.
  • the peripheral speed used is advantageously between 20 m / s and 120 m / s, preferably between 50 m / s and 80 m / s.
  • washing liquid drops in the treatment chamber in connection with a maximum suspended matter separation
  • 1.5 l / m 3 - lo 11m3 of gas to be treated has resulted.
  • the smaller amount of washing liquid is selected in combination with a small average drop size and high peripheral speed of the atomizing plate or cup and vice versa.
  • a device which is characterized in that the individual elements of the rotary atomizer in plate or cup shape are arranged at a distance of 2 mm-10 mm from one another and in their entirety fill the chamber depth.
  • the rotary atomizer elements are arranged on a hollow shaft.
  • the hollow shaft space serves as a feed for the washing liquid.
  • a radial blower impeller is additionally arranged in the chamber, which can be driven by the rotary atomizer shaft or by a shaft independent of it.
  • the treatment chamber in which the method according to the invention runs and in which the aids for carrying out the method are integrated consists of two flat boundary walls perpendicular to the axis of rotation of the gas flow, a spirally expanded or cylindrical boundary wall that is perpendicular to the flat boundary walls stands, the tangential outlet or inlet opening for the gas extending over the entire depth of the chamber.
  • the gas to be treated is fed axially through a treatment chamber 1 through the inlet nozzle 2, which widens conically towards the chamber 1.
  • the washing liquid passes via the pipe 3 practically without pressure from the front part of the shaft 5, which is designed as a hollow shaft and is driven directly or indirectly by a motor 4, on which atomizing plates 6 are fastened at a short distance from one another.
  • the washing liquid reaches the atomizing plate 6 in a uniform distribution, is accelerated there to the circumference as a result of the rotary movement of the atomizing plate 6, and from there, divided into drops, is thrown into the chamber 1.
  • the direction of rotation of the atomizing disks can be chosen to be opposite or, preferably, the same as the direction of rotation of the gas flow, the rotating gas movement resulting from the tangential arrangement of the gas outlet connection 8.
  • the gas to be treated enters the treatment chamber 1 axially through the nozzle 2 and is set in a rapid rotary movement there by the rotating blades 10 attached to the impeller 9.
  • the transfer of the rotary movement to the gas is supported by the washing liquid drops thrown off by the cups 6 of the atomizing device driven by the shaft 5.
  • the bladed impeller 9 is also driven by the motor 4 via the shaft 5.
  • the washing liquid is fed to the atomizer cups 6 via the pipeline 3, from which it reaches the shaft 5, which is designed as a hollow shaft in the front part, and reaches the atomizer cups 6 through the recesses 7.
